                    HelpEvent

A help event is sent when the user has requested context-sensitive help. This can either be caused by the application requesting context-sensitive help mode via wx.ContextHelp, or (on MS Windows) by the system generating a WM_HELP message when the user pressed F1 or clicked on the query button in a dialog caption.

A help event is sent to the window that the user clicked on, and is propagated up the window hierarchy until the event is processed or there are no more event handlers. The application should call event.GetId to check the identity of the clicked-on window, and then either show some suitable help or call event.Skip if the identifier is unrecognised. Calling Skip is important because it allows wxWindows to generate further events for ancestors of the clicked-on window. Otherwise it would be impossible to show help for container windows, since processing would stop after the first window found.
